DARBY, Pa. (CBS) — What security changes,if any, will be made on the campus of Mercy Fitzgerald Hospital in Delaware County in the wake of last week’s deadly shooting inside a medical office?

Hospital officials would not talk about specific security protocols, citing the ongoing investigation, but in an e-mailed statement from a hospital spokeswoman, they say, “We certainly will review our policies and procedures to ensure we do all we can to protect our patients.”

Richard Plotts was able to walk into the Mercy Wellness Center carrying a gun that authorities say he used to killed his mental health caseworker and injure Dr. Lee Silverman before Silverman pulled his own gun and fired back.

The hospital statement goes on to say that Mercy Fitzgerald has “a policy and practice designed to limit weapons on our campus, and we require patients and visitors check firearms with hospital officials during their stay.”

The statement makes no reference to staff.

For now, they say they are focused on supporting and praying for the victims and their families.
